6 monocular cues

Relative height

We perceive objects that are higher in our field of vision to be farther away than those that are lower

Relative size

The size that can object looks (objects that are farther away look smaller to the eye, while objects that are closer up look larger)

Light and shadow

The way light falls on an object and reflects off its surface, and the shadows that are cast by objects are cues for the brain to determine the shape of objects and their position

Interposition

One object partially covers another object, giving the perception the object that is particularly covered is farther away (provides people with the feeling that they are perceiving depth)

Relative motion

as a observer moves forward the objects that appear to move backwards faster are close than apparently slower-moving objects

Stroboscopic movement

visual phenomenon in which viewing a series of slightly varying pictures in rapid succession produces the effect of continuous motion

Phi phenomenon

an illusion of movement created when two or more adjacent lights blink on and off in quick succession

Linear perspective

Type of depth prompt that the human eye perceives when viewing two parallel lines that appear to meet at a distance
